Abstract

In the core of a high capacity network, service differentiation is
still needed to support applications' utilization of the network.
Applications with similar traffic characteristics and performance
requirements are mapped into different diffserv service classes based
on end-to-end behavior requirements of the applications. However,
some network segments may be configured in such a way that a single
forwarding treatment satisfy the traffic characteristics and
performance requirements of two or more service classes. For such
cases, it may be desirable to aggregate two or more service classes
into a forwarding treatment. This document provides guidelines for
aggregation of service classes into forwarding treatments.
